1. A vascular access port comprising:
- a base configured to be attached to a vessel, the base extending in at least a longitudinal direction and a lateral direction that are orthogonal to each other, wherein at least a portion of the base is configured to contact the vessel when the base is attached to the vessel, and wherein a bottom surface of the base is configured to face a wall of the vessel;
an opening that extends through a full thickness of the base and through the bottom surface of the base, wherein the opening is devoid of a closure apparatus, and wherein the portion of the base that borders the opening is non-deformable; and
a body that extends in a vertical direction that is orthogonal to the longitudinal and lateral directions, wherein the body defines at least a portion of a guidance passageway that extends to the opening, and wherein the guidance passageway is larger at the proximal end than it is at the distal end.

Abstract
Ports for accessing vessels within a patient include passageways that can guide needles or other access devices directly into the vessels. The ports can be implanted subcutaneously within a patient. Some ports may be used in the creation and use of vascular access buttonholes.

10. A subcutaneously implantable vascular access port comprising:
-
a base configured to be directly attached to a vessel, the base extending in at least a longitudinal direction and a lateral direction that are orthogonal to each other, wherein at least a portion of the base is configured to contact the vessel when the base is attached thereto; a body extending away from the base in at least a vertical direction that is orthogonal to each of the longitudinal and lateral directions, wherein a height of the body in the vertical direction is sufficiently small such that the entire port can be implanted subcutaneously in a patient; and a guidance passageway that is at least partially defined by the body, the guidance passageway extending from a proximal end to a distal end, wherein the distal end of the guidance passageway defines an opening in a bottom surface of the port, wherein the portion of the port that is immediately adjacent to the opening is non-deformable such that the opening maintains a constant configuration when a medical instrument is inserted therethrough, and wherein an attachment area encompasses at least a portion of the opening. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A vascular access port comprising:
-
a base configured to be attached to a vessel, the base extending in at least a longitudinal direction and a lateral direction that are orthogonal to each other, wherein at least a portion of the base defines a footprint of the port at which the port contacts the vessel when the base is attached to the vessel; a body extending away from the base in at least a vertical direction that is orthogonal to each of the longitudinal and lateral directions, wherein a height of the body in the vertical direction is sufficiently small such that the entire port remains beneath an outer surface of skin after the port has been implanted in a patient; and a guidance passageway that is at least partially defined by the body, the guidance passageway comprising a proximal end and a distal end and defining a central axis that passes through the proximal and distal ends, wherein the guidance passageway is configured to direct an access device into a lumen of a vessel when the port is attached to the vessel, and wherein, when the port is attached to the vessel, the central axis is non-perpendicular and non-parallel to a longitudinal axis of the vessel. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)

30. A vascular access port comprising:
-
a base configured to be attached to a vessel, the base extending in at least a longitudinal direction and a lateral direction that are orthogonal to each other, wherein at least a portion of the base is configured to contact the vessel when the base is attached to the vessel; a body extending away from the base in at least a vertical direction that is orthogonal to each of the longitudinal and lateral directions, wherein a height of the body in the vertical direction is sufficiently small such that the entire port can be implanted subcutaneously in a patient; and a guidance passageway that is at least partially defined by the body and is configured to direct an access device into a vessel of a patient when the port is attached to the vessel, wherein the guidance passageway comprises a proximal end and a distal end and defines a central axis that is non-vertical and nonparallel to the longitudinal direction such that when the base is attached to a vessel, the central axis is at a non-perpendicular and nonparallel angle relative to a longitudinal axis of the vessel, and wherein the guidance passageway is devoid of a closure apparatus. - View Dependent Claims (31)
